Abstract

Apparatus for neutralization of acidic pollutants in flue gas contained in a flue gas channel comprising a flue gas channel for containing a flue gas, a suspension feed pipe having a delivery opening and being connected to apparatus for preparing and maintaining an erosive suspension of a finely divided basically reaction solid in a liquid for introducing suspension as such into the flue gas channel, a compressed gas pipe having a gas discharge opening, said opening being positioned to discharge gas so as to atomize the suspension after it has exited the delivery opening, a device for determining the amount of flue gas flowing through the channel and the amount of pollutants therein and apparatus for simultaneously and separately controlling the amount of suspension introduced and the concentration of said suspension and the amount of compressed gas used depending on the determined amount of flue gas, pollutants, or flue gas and pollutants in the flue gas channel.
